Public Methods

Method	Description
DecryptSEBSettings ( byte sebData, bool forEditing, string &sebFilePassword, bool &passwordIsHash, X509Certificate2 &sebFileCertificateRef ) : Dictionary,System.Collections.Generic	Decrypt and deserialize SEB settings When forEditing = true, then the decrypting password the user entered and/or certificate reference found in the .seb file is returned
EncryptDataUsingIdentity ( byte data, X509Certificate2 certificateRef ) : byte[]	Encrypt preferences using a certificate
EncryptDataUsingPassword ( byte data, string password, bool passwordIsHash, SEBSettings configPurpose ) : byte[]	Encrypt preferences using a password
EncryptSEBSettingsWithCredentials ( string settingsPassword, bool passwordIsHash, X509Certificate2 certificateRef, SEBSettings configPurpose, bool forEditing ) : byte[]	Show SEB Password Dialog Form. Read SEB settings from UserDefaults and encrypt them using provided security credentials
GetPrefixDataFromData ( byte &data, int prefixLength ) : byte[]	Helper method for stripping (and returning) a prefix byte array of prefixLength from a data byte array which is returned without the stripped prefix
GetPrefixStringFromData ( byte &data ) : string	Helper method for returning a prefix string (of PREFIX_LENGTH, currently 4 chars) from a data byte array which is returned without the stripped prefix
StoreDecryptedSEBSettings ( byte sebData ) : bool	Decrypt, parse and use new SEB settings

Private Methods

Method	Description
DecryptDataWithPasswordForConfiguringClient ( byte sebData, bool forEditing, string &sebFilePassword, bool &passwordIsHash ) : Dictionary,System.Collections.Generic	Helper method which decrypts the byte array using an empty password, or the administrator password currently set in SEB or asks for the password used for encrypting this SEB file for configuring the client
DecryptDataWithPublicKeyHashPrefix ( byte sebData, bool forEditing, X509Certificate2 &sebFileCertificateRef ) : byte[]	Helper method which fetches the public key hash from a byte array, retrieves the according cryptographic identity from the certificate store and returns the decrypted bytes
GetPreferencesDictFromConfigData ( byte sebData, bool forEditing ) : Dictionary,System.Collections.Generic	Helper method: Get preferences dictionary from decrypted data. In editing mode, users have to enter the right SEB administrator password before they can access the settings contents and returns the decrypted bytes
askForPasswordAndCompareToHashedPassword ( string sebFileHashedAdminPassword, bool forEditing ) : bool	Ask user to enter password and compare it to the passed (hashed) password string Returns true if correct password was entered
